If your Dyson V8 is showing signs of trouble — Reduced suction, musty odor — it's likely time for a hepa filter replacement. Manufacturers recommend replacing it Every 12 months, though heavy use can shorten that window significantly.

Below we've compared every available option: the original Dyson part and the top-rated compatible alternatives, so you can make the right call for your budget and usage.

About the Dyson V8

The Dyson V8 cordless has a post-motor filter downstream of the motor, in addition to the washable purple pre-motor filter on top. This page covers the post-motor (HEPA-grade) filter — the sealed final stage.

🔎 Dyson V8 hepa filter — what to know

The V8 post-motor filter sits at the rear of the machine and is washable in most builds, but it clogs and ages more slowly than the pre-filter. Replace it when washing no longer restores airflow — a spent post filter both restricts suction and lets fine dust escape.

✓ Buying Advice

Genuine Dyson guarantees the seal that keeps the V8 truly sealed; aftermarket post filters are cheaper and fine when the listing names the V8. Refresh both filters together for a complete reset.

⚠ Common Mistakes

The V8 mistake is only ever cleaning the purple pre-filter and never the post-motor one, so allergens build up. The second is refitting either filter damp — 24-hour air-dry, no detergent, no hot water.

Frequently Asked Questions

How often should I replace the Dyson V8 hepa filter?
Dyson suggests replacing the V8 hepa filter Every 12 months under normal use — sooner with pets or daily heavy use. Signs it's due: Reduced suction, musty odor. Wash/replace the V8 post-motor filter when it won't rinse clean — on its own, less-frequent schedule from the purple pre-motor filter; dry 24 hours before refitting.
Can I just wash the V8 hepa filter instead of replacing it?
Often, yes — many vacuum filters are washable. Rinse under cold water only (no detergent, no hot water), squeeze gently and air-dry fully — a full 24 hours for Dyson filters — before refitting. Replace it when it won't rinse back to clean, the foam crumbles, or the pleats/mesh are damaged; a washable filter still wears out eventually.
Do I have to buy the genuine Dyson part, or will a compatible one work?
Yes — a compatible (aftermarket) hepa filter works well in the Dyson V8 as long as it's made for this exact model. Genuine Dyson guarantees the seal that keeps the V8 truly sealed; aftermarket post filters are cheaper and fine when the listing names the V8. Refresh both filters together for a complete reset.
How much does a Dyson V8 hepa filter cost?
Compatible hepa filter options for the Dyson V8 start around $6.99. The prices in the table above are checked against Amazon regularly; multipacks usually cost less per unit.
What's the most common mistake when replacing the V8 hepa filter?
The V8 mistake is only ever cleaning the purple pre-filter and never the post-motor one, so allergens build up. The second is refitting either filter damp — 24-hour air-dry, no detergent, no hot water.
